Missing Keyboard Shortcuts in Outlines

I love the Outlines feature in Toodledo and have been using it since it was introduced. Originally, there were a number of keyboard shortcuts that could be used to navigate an outline via the keyboard. For example, the "J" and "K" keys were used to move up and down the outline, "C" added a child element, and so forth. These keyboard shortcuts seem to have been removed as they are no longer displayed nor do they work, and without them, I find outlines harder to navigate.

I noticed this a few weeks ago after I reported other, more serious problems with Outlines that were resolved. I'm wondering if the keyboard shortcuts were removed as part of the fix to the other problems.

In any case, what happened to these navigational keyboard shortcuts in Outlines, and are they coming back?
